Besides, the game machine 1 has in the computer 7 a distributing word information producing means 41, a rank information producing means 42 and a ranking computing means 43.

Each arrow connected between the respective means in FIG. 1 is only for easy understanding of the invention, so that exchanges of information and processing between the respective means are not limited by these arrows.

Operations of the game machine 1 according to the invention are now explained, referring to FIG. 2. The game in the game machine 1 which is now explained is a so-called adventure game which has the story information 28 wherein a player, a detective, is instructed to search a criminal in a case together with a character in the game.

When initial status explanation of the game being published on a magazine or a predetermined homepage, for instance, each player who wishes to play this game by watching the publication accesses a predetermined homepage through the mobile phones 3A, 3B or the personal computer 3C and sets (registers) an E-mail address to be used in the mobile phones 3A, 3B or the personal computer 3C on the web.

Then, a proper E-mail address (that is, the E-mail address of the mobile phones 3A, 3B or the personal computer 3C) and a proper story proceeding status for a player (that is, the story proceeding status for each E-mail address of the mobile phones 3A, 3B and the personal computer 3C) which are to be stored in and controlled by the player information control means 25 are set (registered) in a memory medium (not shown) such as a hard disc. The story proceeding status at this time is set as “initial status”.

After finish of setting (register) in the player information control means 25, the story processing means 18 may process such that the story proceeding status is in “the initial status”, the reply mail preparing means 19 may prepare a replay mail for requesting an initial instruction, and the replay mail processing means 20 may send the reply mail to the mobile phones 3A, 3B or the personal computer 3C through the sending server 13.

Any method of first setting a state of a progress of the story for each player is available as long as the state of the progress of the story for the player who wants to play the game can be set as “the initial state”. For instance, an E-mail address of the game machine 1 is published and the player sends an E-mail showing the player wants to play so as to set the state of the progress of the story for each player as “the initial state”. Alternatively, a letter showing the player is willing to play is sent via a mail and then, an operator operates the computer 7 so as to set.

When finishing setting (register) in the player information control means 25, each player can start to play the game. If the player having the mobile phone 3A starts to play the game, the player prepares an E-mail having sentences of instructing a character in the game and send this to the e-mail address of the game machine 1 in order to develop a story of the game.

Preferably, the e-mail prepared by the player can be analyzed by the sentence analyze means 17 of the instruction obtaining means 16, which is mentioned hereinafter. Then, the distributing word information producing means 41 produces information of a plurality of words which is stored in the corresponding word storing means 26, corresponding to instruction information as word information to be informed so as to be displayed on a predetermined homepage in the shape of a list so that it can be informed through the web server 40, that is, so that is can be confirmed when accessing the web server 40 from the mobile phone 3A (or the mobile phone 3B or the personal computer 3 c).

The above-mentioned information of a plurality of words is comprised of a plurality of words to be used as instruction information, that is, words of character name, such as “Mr.A”, “Ms.B”, “Miss.C”, words of place name, such as “the scene of an offense”, “. . . office”, “. . . police station”, words of noun, such as “knife”, “article left”, “photograph”, words of verb, such as “gone”, “taken”, “sent”, and words indicating time, such as “one o'clock”, “half past one”, “two”, and the corresponding word storing means 26 controls the word information together with information of player's instruction (so-called “command”) which corresponds to each word.

The word information may be informed with a list in a predetermined homepage. Besides, it may be downloaded as dictionary conversion information or stereotyped sentence information in each terminal unit 3.

If the player having the mobile phone 3A prepares “Mr. A, go to the scene of the offense at two” as an E-mail and send it to the E-mail address of the game machine 1, the receiving server 12 receives it (this E-mail will be referred to as “the receiving mail” hereinafter) through the Internet 2. Then, the player having the mobile phone 3A is identified as an origin of the receiving mail (the E-mail address of the mobile phone 3A) by the player identification means 15. When the player having the mobile phone 3A being identified, the proceeding control means 21 obtains a state of a progress of story which corresponds to the player out of information of progresses of the respective players which is controlled by the player information control means 25 so as to judge the state of the progress of the player.

On the other hand, the sentence analysis means 17 of the instruction obtaining means 16 divides the above-mentioned E-mail into a plurality of words, such as “Mr. A”, “go”, “to a scene of the offense”, “at two”, and checks the E-mail against the information of a plurality of words stored in the corresponding word storing means 26 so as to analyze the contents of the sentence. The instruction obtaining means 16 obtains instructions (commands) corresponding to the respective words with this analysis and collectively processes a plurality of instructions (commands) related to a plurality of words, so that it can obtain the receiving mail as instruction information.

When thus obtaining the instruction information from the receiving mail by the instruction obtaining means 16, the story processing means 18 processes the development of the story of the game on the basis of the obtained instruction information and the state of the progress of the story judged by the proceeding control means 21, referring to the story information 28 and the character information 29 which are controlled by the story information control means 27.

The story processing means 18 judges as to whether or not Mr.A can go to the scene of the offence at two in the game on the basis of the instruction information obtained from the receiving mail and the state of the development of the story in the last processing. When the judgment is yes, it processes future story which can be developed by getting Mr.A to go to the scene of the offense at two. On the contrary, if Mr. A can not go to the scene of the offense at two according to the last processing on the development of the story, that is, if Mr. A is taking the other action in the game or is at a place remote to the scene of the offense, it processes future story which can be developed by getting Mr. A not to go to the scene of the offense at two. The result processed by the story processing means 18 is controlled by the proceeding control means 21 and is stored in the player information control means 25 as the state of the progress of the story for the player who has the mobile phone 3A.

Subsequently, the reply mail preparing means 19 prepares information of reply in response to the instruction information obtained from the receiving mail according to the development of the story processed by the story processing means 18 as a reply mail. That is, in the processing by the story processing means 18, a reply mail “I see” if Mr. A can go to the scene of the offence at two, or the reply mail “It's impossible” if not is prepared, and the reply mail prepared is outputted to the reply mail processing means 20. At the same time, the reply mail “just received” is also prepared if yes so as output to the reply mail processing means 20.

And, the reply mail processing means 20 sends the reply mail prepared by the reply mail preparing means 19 to the mobile phone 3A through the sending server 13. At this time, the reply time processing means 24 computes a time for sending the reply mail to the mobile phone 3A on the basis of the development of the story processed by the story processing means 18 for each reply mail, and allows the reply mail processing means 20 to send the reply mail when it comes time to send the reply mail.

That is, the reply time processing means 24 immediately allows the reply mail processing means 20 on the basis of the processing by the story processing means 18 to send the reply mail which is not related to time in the development of the story, such as “I see” or “It's impossible”, and the reply mail processing means 20 immediately sends the reply mail to the mobile phone 3A. On the other hand, the reply time processing means 24 does not allow the reply mail processing means 20 on the basis of the processing of the story processing means 18 to send the reply mail which is related to time in the development of the story, such as “just reached” before two o'clock in the actual time and allows at two o'clock, so that the replay mail is sent to the mobile phone 3A by the reply mail processing means 20.

Subsequently, for instance, the player having the mobile phone 3B prepare “Ms. B, send a photograph of . . . office to me” as an E-mail, and send it to the E-mail address of the game machine 1, and the receiving server 12 receives it as the received mail through the Internet 2. Then, the player having the mobile phone 3B is identified as an origin of the received mail (that is, the E-mail address of the mobile phone 3B) by the player identification means 15, and the proceeding control means 21 obtains a state of a progress of story which corresponds to the player out of information of progresses of the respective players which is controlled by the player information control means 25 so as to judge the state of the progress of the player.

And, the sentence analysis means 17 of the instruction obtaining means 16 checks the received mail and the information of a plurality of words which is stored in the corresponding word storing means 26 so that the contents of the sentence can be analyzed, and with this analysis, the instruction obtaining means 16 obtains the received mail as instruction information. The story processing means 18 processes the story of the game to be developed by sending a photograph of . . . office by Ms. B according to the obtained instruction information and the state of the progress of the story judged by the proceeding control means 21, referring to the story information 28 and the character information 29 which are controlled by the story information control means 27.

Subsequently, the reply mail preparing means 19 prepares the reply mail, such as “I will send a photograph of . . . office” as information in response to the instruction information obtained from the received mail on the basis of the development of the story processed by the story processing means 18. At this time, the reply mail preparing means 19 obtains an image of “. . . office” out of a plurality of images controlled by the image information control means 30 which are related to the story of the game, and attaches the image to the replay mail as an attached file.

Such an image is not always attached by the reply mail preparing means 19 on the basis of the instruction information from the player (contents of sentence of received mail). Preferably, when the story processing means 18 develops the story, such as when a new accident happens, a predetermined image is attached according to the development of the story.

The reply mail processing means 20 immediately allows the reply time processing means 24 to send the above-mentioned reply mail since it does not relate to time, and the reply mail with the above-mentioned image attached by the reply mail preparing means 19 is sent to the mobile phone 3B through the sending server 13.

If the player having the personal computer 3C prepares a sentence “ABCDEFGHIJ . . . ” as an E-mail and sends it to the E-mail address of the game machine 1, the receiving server 12 receives it as a received mail through the Internet 2. Then, the player having the personal computer 3C is identified as an origin of the received mail (the E-mail address of the personal computer 3C) by the player identification means 15.

Subsequently, the sentence analysis means 17 of the instruction obtaining means 16 checks the above-mentioned received mail and the information of a plurality of words which is stored in the corresponding word storing means 26 so as to analyze the contents of the sentence. But, the instruction obtaining means 16 is impossible to analyze this received mail and impossible to obtain instruction information from the received mail since there is no word corresponding to the received mail. Then, the error judging means 22 judges that the instruction obtaining means 16 can not analyze the contents of the sentence of the received mail, and receiving this judgment, the error mail preparing means 23 prepares an error mail, such as “I don't know. Please send again.”.

The reply mail processing means 20 immediately allows the reply time processing means 24 to send the error mail since it is not related to time, and the reply mail preparing means 19 sends this error mail to the personal computer 3C through the sending server 13. In such a case, the story processing means 18 does not develop the story since the instruction obtaining means 16 is impossible to obtain instruction information.

As mentioned before, the story proceeds in such a manner that each player sends an E-mail to the game machine 1, the development of the story is processed, with the state of the progress of the story being controlled every each player, a reply mail (error mail) is prepared on the basis of the development of the story, and each player receives the reply mail (error mail).

On the other hand, the ranking computing means 43 computes a rank of each player in the game according to the state of the progress for each player which is stored in and controlled by the proceeding control means 21 and the player information control means 25, and the rank information producing means 42 produces the computed ranks of the players as ranking information so as to show a ranking list on a predetermined homepage. In other words, when accessing the predetermined homepage by each player, the above-mentioned ranking list can be obtained through the Internet 2 and the web server 40. That is, when accessing the web server 40 from the mobile phones 3A, 3B or the personal computer 3C, each player can see the ranking list.

The ranking information produced by the rank information producing means 42 includes ranking information for all players. But, this information may include only a rank for a player who accesses the web server 40, or may include only ranks for the players in upper rank (that is, the players whose progresses of the story are faster).

According to the game machine 1 in the invention, the instruction obtaining means 16 analyzes contents of the sentence in the received mail so as to obtain as instruction information, the state of the progress of the story corresponding to the player is judged by the story processing means 18 and the story information control means 27, the development of the story in the game is processed on the basis of the judged state of the progress and the instruction information, the reply mail to be sent as information in response to the instruction information is prepared on the basis of the development of the story which was processed by the reply mail preparing means 19, and the reply mail prepared by the reply mail processing means 20 is sent to the player, so that the player can easily start the game and play the game without preparing a game program as long as the player has the terminal unit 3 through which an E-mail can be sent and received. Besides, the terminal unit 3 is not necessary to have a game program. So, the game with a lot of funs can be played with the mobile phone 3A, 3B even if the capacity or storage capacity thereof is low.

And, the sentence analysis means 17 analyzes the contents of the received mail by checking the contents of the received mail and a plurality of words corresponding to the instruction information, so that the instruction information can be obtained from the received mail.

Besides, the error judging means 22 judges impossibility of analysis of the contents of the received mail, and the error mail preparing means 23 prepares and sends the error mail, so that the player can confirm that the development of the story has not been processed, and can play the game smoothly.

Furthermore, the reply time processing means 24 computes time for sending the reply mail according to the processing of the development of the story, and allows the reply mail processing means 20 to send the reply mail when it comes time to send, so that the development of the story in the game can be matched with the actual time so as to feel for the player that the story in the game is in the actual world.

And, at the time of preparing the reply mail, the reply mail preparing means 19 prepares the reply mail with a predetermined image information attached on the basis of the processing of the development of the story, so that the player can confirm the development of the story with the image in addition to sentences, thereby increasing the funs of the game.

Besides, the distributing word information producing means 41 produces information of a plurality of words which is stored in the corresponding word storing means 26 as the word information to be delivered through the web server 40, so that the player can obtain the word information through the Internet 2, and the player can prepare an E-mail on the basis of this word information so as to analyze the sentence for the instruction obtaining means 16 and to obtain the instruction information. Then, the instruction obtaining means 16 does not fail to obtain the instruction information, thereby smoothly playing the game.

Furthermore, the ranking computing means 43 computes the ranks of the players in the game according to the state of the progress of the story for each player which is stored in and controlled by the proceeding control means 21 and the player information control means 25, and the rank information producing means 42 produces the ranks of the players as the rank information to be distributed through the web server 40, so that the player can obtain the ranking information through the Internet 2. Then, the player can confirm the player's own rank or the players in the upper rank, thereby giving the player a willing for advancing the game.
